Questions

Is there a KiCad symbol and footprint for the BC549C?

Yes. The symbol is Transistor_BJT:BC549 and the footprint Package_TO_SOT_THT:TO-92_Inline, both drawn on this page. PCBKit places them on a board for you when you design with it.

What can replace the BC549C?

Parts like it in the library: the S8050T by XCH, the DS18B20 by DALLAS MAXIM, the DS18S20 by DALLAS MAXIM and the BC550CTA by FAIRCHILD. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BC549C?

4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
